Mass storage devices: Video servers use high-speed, broadband SCSI interface hard drives or state-of-the-art FC interface hard drives as AV storage media. At the same time, the hard disk expansion of video and audio data is also flexible.
Input/Output Channel: The video server has a multi-channel input/output system, enabling multiple recording and playback to be performed simultaneously for multitasking.
Network interface: The video server has a network interface to facilitate networking and data sharing. General video servers come with FC and Ethernet interfaces. The FC optical network uses the IP protocol as a switching network for fast, real-time replication and moving of materials between video servers. Ethernet is used to transmit control data and status detection information.
Video and audio interface: The video server has a standard video and audio interface and an analog surveillance video interface to monitor the video signals of each channel. Input/output signals can be selected in analog, component, and SDI.
RS422 serial interface: The video server has multiple RS422 serial communication interfaces, and each interface can be recorded and played by an external computer through the RS422 communication line.
Protocol Interface: In addition to providing various control hardware interfaces, the video server also provides a protocol interface. For example, the RS422 interface supports the RS422 profile protocol, and also supports protocols such as Louth, Odetics, and BVW that are controlled by RS422.
Software Interface: The video server provides an open software interface for users or third-party vendors to develop and build new applications.
Video and audio crosspoint matrix: video and audio crosspoint matrix in the video server, visual and audio channel scheduling flexibility, while ensuring that technical indicators are not damaged.
In addition, the video server provides external lock phase and video processing functions to facilitate the construction of audio and video systems for specialized applications.
The PU foam is the most advanced and eco-friendly insulation material in the world. With the help of the back aluminum foil, the thermal preservation effect achieves the best.
The unique structure prevents the heat loss in winter. Meanwhile it reduces the heat of the summer sunshine.
Aceta paintcoat and flurocarbon paint of weather resistance performance are applied on surface of wall panel. It is reserved with superior self-cleaning, weather resistance, corrosion resistance and acid& alkali resistance performance.
Light weight with 3.7Kgs/m2 makes the installation easy.
The installation process is clean and tidy without any noise and dust, construction waste.
Different selections of accessories meet different effects.
